J9991A Use Case
High-Density Wi-Fi 6 Access Point Uplinks with J9991A-20P POE+
In a large enterprise campus deploying Aruba Wi-Fi 6 APs, the J9991A-20P POE+ module delivers 30 W per port across 20 PoE+ ports and four 1/2.5/5 Gbps XGT uplinks. This all-in-one solution eliminates external power injectors, reduces cabling complexity and removes bottlenecks by aggregating traffic at multi-gig speeds. The outcome is seamless, high-throughput wireless coverage for thousands of concurrent users with simplified operations and lower total cost of ownership.
Smart Video Surveillance for City Traffic Management
In a municipal traffic control center, the J9991A-20P POE+ module powers and connects 4K PTZ and AI-enabled cameras requiring up to 30 W per port while the four XGT ports handle real-time video streams at up to 5 Gbps. By centralizing power delivery and multi-gig aggregation, this deployment eliminates separate power supplies, minimizes network latency and ensures uninterrupted analytics. The result is reliable, high-resolution monitoring with streamlined infrastructure and reduced maintenance overhead.
Telemedicine and Medical IoT in Acute Care Facilities
In a hospital’s critical care wing, the J9991A-20P POE+ module powers telemedicine carts, VoIP phones and patient-monitoring sensors at 30 W per port and transports EMR and high-definition video over its four 1/2.5/5 Gbps uplinks. This single-chassis approach meets medical-grade reliability, supports real-time data transfer and eliminates dedicated power cabling. The benefit is accelerated patient care, simplified compliance with healthcare standards and reduced rack footprint for IT teams.
